HMS1 Ref. 1LCAW.S03A.C111W

With its understated simplicity, the HMS1 line is a modern take
on Arnold & Son's traditionally elegant design combined with
superior craftsmanship. Housed in a classically styled 40 mm case
with see-through back, the hand-wound A&S1001 calibre is
manufactured in-house and decorated with either straight or
radiating (rayonnantes) Côtes de Genève guilloche. The movement is
2.7 mm in thickness with twin barrels generate a minimum power
reserve of 90 hours and a more constant force, hence greater
accuracy the whole time the movement is running.

Blued screws in the rhodium-plated movement, mirror-polished
screws in the NAC grey version, and specific decorations for each
version testify to the attention to detail. The HMS1 collection
comes in a range of dial colours and with various finishes
depending on the model, as well as a choice of cases in 18-carat
white gold, 18-carat rose gold or stainless steel. It is also
available with an exquisite diamond-set bezel.
